I am new to R and have a problem that I haven't been able to find the answer to in the guides or online.

I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, and I would like to produce two plots side by side using mfrow.  The first plot should contain data from D1-D4, the second should contain D5-D8.

I can plot these separately using the code,

par(mfrow=c(1,1))
plot(c(0.000001,1),c(0,100),type="n", xlab="D", ylab="% R", log="x")
     points(D1$L0,D1$K1_R1,lwd=2, col="blue", )
     points(D2$L0,D2$K1_R2,lwd=2, col="red", )
     points(D3$L0,D3$K1_Rt3,lwd=2, col="orange", )
     points(D4$L0,D4$K1_R4,lwd=2, col="black", )

or

par(mfrow=c(1,1))
plot(c(0.000001,1),c(0,100),type="n", xlab="D", ylab="% R", log="x")
     points(D5$L0,D1$K2_R1,lwd=2, col="blue", )
     points(D6$L0,D2$K2_R2,lwd=2, col="red", )
     points(D7$L0,D3$K2_Rt3,lwd=2, col="orange", )
     points(D8$L0,D4$K2_R4,lwd=2, col="black", )

but how can I plot them together?

Thanks in advance for your help, I appreciate any help you can give.
